Description

Hepatobiliary pancreas patient wound hemostasis device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a postoperative wound hemostasis device for a patient with hepatobiliary pancreas.

Background

When a patient is clinically subjected to hepatobiliary pancreatic surgery, the wound needs to be immediately stopped after a section is cut by a scalpel, the conventional stopping method is electrocoagulation stopping, the stopping method can stop bleeding through electrocautery stopping points, stopping bleeding can be achieved within 1-2 seconds, the bleeding amount of the patient is small due to the fact that the operation is simple, the stopping speed is high, and the patient becomes the conventional stopping method for the surgery.

The aseptic sponge that present commonly used medicine hemostasis method needs the reuse to dip in the hemostatic or change the aseptic sponge that has soaked the hemostatic in advance and just can accomplish the hemostasis operation, and above-mentioned process operation step is many, and the duration is long, has the waste of different degrees to aseptic sponge and hemostatic. Still lack among the prior art and can continuously provide hemostatic to aseptic sponge, and can practice thrift hemostatic device.

In order to solve the problems, the prior art CN 110960316B discloses a rapid hemostasis device for hepatobiliary surgery, which comprises a drug hemostasis part and an electric coagulation hemostasis part arranged on a handle, wherein the drug hemostasis part comprises a drug supply bin filled with a hemostatic agent and a constraint bin communicated with the drug supply bin and used for constraining an aseptic sponge, the hemostatic agent is guided into the constraint bin by the drug supply bin and then soaked into the aseptic sponge in the constraint bin, when hemostasis is needed, the aseptic sponge soaked with the hemostatic agent is contacted with a bleeding point by a handle held by an operator to achieve the purpose of hemostasis, the prior art simplifies the hemostasis operation steps, and the aim of continuously supplying drugs to the aseptic sponge is fulfilled.

However, the above prior art has the following drawbacks: the sponge in the prior art is fixed, the hemostat hemostasis is generally realized by accelerating the coagulation of blood through the coagulation factor in the hemostat, and during the actual operation, because the wound area in the hepatobiliary pancreas operation is not large, when the hemostasis device in the prior art is used by an operator for hemostasis operation, the same area on the sterile sponge is contacted with a bleeding point for hemostasis every time, when the sponge with the hemostatic contacts the bleeding point of the human tissue to stop bleeding, blood can adhere to the contact area on the sponge and quickly coagulate to block the pores on the sponge, so that the hemostatic can not flow out from the contact area any more, further, the aim of stopping bleeding by continuously contacting the bleeding point with the sponge cannot be achieved, and in order to continue stopping bleeding, the operator needs to continuously adjust the arm movement to contact the bleeding point with different surface areas on the sponge so as to achieve the aim of stopping bleeding at the bleeding point.
